I can't attest to the technical explanation but I can add a "Me Too!"  
My phone line mysteriously died yet my DSL worked just fine.  The cause 
of the fault was that an urban fox gnawed my phone cable, which looped a 
little in the porch, severing several wires including one of the main 
pair...  Thankfully BT didn't charge me :)
